Fix #447: Resolve DVB split mode crash and routing logic

- Fixed NULL pointer dereference in dvb_subtitle_decoder.c (sub->prev check).
- Corrected logic in dvbsub_handle_display_segment to prevent dropped subtitles.
- Implemented robust encoder context swapping in general_loop.c for DVB streams.
- Added regression test: tests/regression/dvb_split.txt.
- Verified 100% completion in split mode and correct Teletext/DVB routing.
